Abstract:

Objective

To systematically evaluate the availability and safety of single incision versus conventional multiport laparoscopic cholecystectomy.

Methods

Electronical search CBM, CNKI, PubMed, EMbase, The Cochrane Library, screened for randomized controlled trials(RCT) comparing single incision laparoscopic cholecystectomy(SILC) and conventional multiport laparoscopic cholecystectomy(CMLC) until Jul. 2015.The RevMan5.3 software was used for meta-analysis.

Results

We included 34 trials involving 2 951 patients: 1 502 to SILC versus 1 449 to CMLC.Meta-analysis revealed that the operative time in SILC group was longer than that in CMLC group[MD=11.56, 95%CI(8.97, 14.16), Z=8.75, P<0.000 01]. Compared with CMLC group, SILC group was higher in conversion rate[RR=4.01, 95%CI(2.56, 6.29), Z=6.06, P<0.000 01]. Furthermore, wound satisfaction score was [SMD=1.34, 95%CI(0.74, 1.94), Z=4.39, P<0.000 1.There was no significant difference between SILC group and CMLC group for blood loss, postoperative complications, 24 h postoperative pain score, hospital stay and time to return to work(P> 0.05).

Conclusions

SILC is a safe and effective surgical procedure with the advantage of a better cosmetic result.However, SILC requires surgeon’s skill and experience to reduce operative time and conversion rate.
